Stainless steel angle steel can be assembled into various structural components to meet different structural requirements and also serves as connecting elements between components. It is widely used in various architectural and engineering structures, such as beams, bridges, transmission towers, lifting and conveying machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves.

Stainless steel angle steel is a carbon structural steel used for construction, featuring simple cross-section profiled steel. It is primarily used in metal components and the frames of buildings. It requires good weldability, plastic deformation properties, and certain mechanical strength for use. The raw material for producing stainless steel angle steel is low-carbon square billets, with the finished product being delivered in a hot-rolled, normalized, or hot-rolled condition.

Types and specifications mainly include two categories: equal leg stainless steel angles and unequal leg stainless steel angles. The unequal leg stainless steel angles further divide into two types: unequal leg equal thickness and unequal leg unequal thickness.

Stainless steel angle iron specifications are denoted by the dimensions of the side length and thickness. Since 2010, domestic stainless steel angle iron specifications range from 2 to 20, with the number indicating the centimeters of the side length. The same number often features 2 to 7 different thicknesses. Imported stainless steel angle iron is marked with the actual dimensions of both sides and the thickness, along with relevant standards. Generally, angle irons with a side length of 12.5cm or more are considered large, those between 12.5cm and 5cm are medium, and those with a side length under 5cm are small.
